      Hi, not sure if this is expected behavior or not but my delta backup job always leaves a snapshot there, is this correct behavior? My understanding was that it would remove the snapshot after the successful backup?

        Well everything is moved over to an NFS datastore, thanks for the responses all
        Performance seems unchanged (which is great)

          @jmannik Yes, the delta backup should leave a single snapshot for every VM.

            @Andrew Thanks, I thought as much... time to buy some bigger disks then I guess.

              Or to switch to thin based storage. In that case, a snapshot won't use extra space 🙂

              And yes, the snapshot left is the reference since the last backup.

                  Testing with my workloads (game servers), NFS performance is not as good as iSCSI performance, but it has crossed my mind to revisit and test further (previous testing was in ESXi/vSphere v7).... but to do that I need to buy more disks.
                  Planning on adding 4x4tb sas ssd's to my storage server to migrate everything off the 17x480gb ssd array. and slowly build out the new array with additional disks over time

                    Perf is equal, just test it twice so the penalty disappear (inflating the VHD). In production usage, the diff is less than few % tops.

                      @olivierlambert Just letting the latest backup job complete and will start resizing some things on the storage to start shuffling things over
